Refrigerant Leak CO2e Estimator

Estimate Scope 1 refrigerant leak emissions using leaked mass and a GWP factor you choose.

Educational only. GWP values vary by standard (AR4/AR5/AR6). Use the GWP required for your reporting method.

How to use this tool

  1. 1Choose a refrigerant name and enter leaked mass.
  2. 2Enter the GWP factor used in your reporting method.
  3. 3Calculate tCO2e and export results.
  4. 4Store evidence links for audit readiness.

What the results mean

Refrigerant emissions can dominate Scope 1 in some operations.

Credibility comes from: consistent event logging, documented GWP choice, evidence links (service records, invoices).

Common pitfalls

  • Using the wrong GWP standard for your reporting boundary
  • Confusing "charged refrigerant" with "leaked refrigerant"
  • Not recording event date and evidence (hard to audit later)
  • Double counting leaks and recharges
